Boxing icon Muhammad Ali (pictured) was released from a hospital Tuesday night after being admitted nearly three weeks ago with what was presumed to be pneumonia. Now it is being reported that the champ was being treated for a severe urinary tract infection, according to NBC News.

The 72-year-old, three-time world heavyweight champ also suffers from Parkinson’s disease, a debilitating neurological illness that has practically stilled his voice and slowed his movements for the last 30 years.

Reportedly, Ali is back home with his family and is now looking forward to celebrating his 73rd birthday on January 17. Ali’s spokesperson, Bob Gunnell told ESPN, “He’s in great spirits and enjoying being back home.” Gunnell said. “He’s back in his daily routine.”

Even though Ali’s public profile has been low over the last few years, he still manages to get out every now and then. Last September Ali was spotted at an outing where he sat in the bleachers supporting his grandson, Biaggio Ali Walsh, as the latter played football alongside Cordell Broadus, the son of famed rapper, Snoop Dogg. The two young players with famous bloodlines are reportedly stellar gridiron athletes with scholarship potential.

Meanwhile, according to Gunnell, the Ali family is thankful for the show of love and support for the champ from well-wishers everywhere. “The Ali family greatly appreciates the outpouring of support and continued well wishes. They also want to thank the team of doctors and nurses for their exceptional care,” he said.
